Further TXA 2 is a powerful vasoconstrictor against bronchus and bronchial smooth muscle. Therefore, TXA 2 is considered to take part in pathological conditions over a wide range. As examples, the following diseases can be exemplified.
  • myocardial infarction for example, myocardial infarction, angina pectoris, and thrombosis
  • transient ischemic attack migraine, cerebral hemorrhage, and cerebral infarction
  • Atherosclerosis For example, atherosclerosis, capillary convulsion, peripheral circulation disorders, hypertension, and pulmonary embolism
  • bronchial asthma for example, bronchial asthma, bronchitis, pneumonia, nephritis, and hepatitis
  • compounds that antagonize the action of TXA 2 are expected to have therapeutic effects in preventing or treating one or more of the diseases described above or other diseases involving TXA 2 . Furthermore, in those instances where use of a particular drug was limited due to side effects mediated by TXA 2 or considered to be mediated by TXA 2 , it is expected to alleviate the side effects by the use of compounds which antagonize the action of TXA 2 .
  • TXA 2 is also thought to play a role in the pathogenesis of allergic diseases, especially of an asthma [cf. J. Allergy Clin. Immunol., 77, 122 (1986); Arch. Pharmacol., 327, 148 (1984)].
